Timinig Chain vs Timing Gears

I have a 99 Tahoe with a 5.7L Vortec and was wondering what the overall opinion was on timning gears vs a timing chain. I am starting to do some engine work and was looking to do gears rather than a chain.

There will also be a noticeable gear whine not unlike a blower whine at low rpms. Don't know what they sound like at higher rpms tho.

They make quieter versions these days, though I personally do not know how much quieter. I once wanted a Pete Jackson till I heard one. OK for racers, but I do not think you would want one in a Daily Driver. A double roller is more than enough.
